MAP for Blood Pressure 100/65 mmHg
A blood pressure of 100/65 mmHg yields a mean arterial pressure of approximately 77 mmHg.
How to use this tool
- Enter your systolic (top) blood-pressure number.
- Enter your diastolic (bottom) blood-pressure number.

Frequently asked questions
- What is a normal mean arterial pressure?
- For most adults MAP sits roughly between 70 and 100 mmHg. A MAP around or above 60 mmHg is often described as the minimum needed for adequate organ perfusion, but individual targets vary.
- Why is diastolic pressure weighted twice in the formula?
- At resting heart rates the heart spends about two-thirds of each cycle in diastole, so the average pressure is closer to the diastolic value, which the (SBP − DBP)/3 term captures.
- Is this MAP the same as an arterial-line MAP?
- It is a close estimate at normal heart rates. A true arterial-line MAP integrates the whole pressure waveform and can differ, especially when the heart rate is fast.
